01 Polaris 90 Sportsman Pilot Setting

[kdagenais]

Just wondering if anyone can tell me what the pilot jet setting should be ( 1 1/2 turn)? Also explain to me how the choke works on this thing? Just picked this thing up for $200 and is in pretty good shape guy didn't realize the tether cord switch wasn't working properly and thought the CDI was bad.
Would love to have a wiring schematic to but not necessity at this time.
Thanks In Advance!

Pilot jet starting point is good at 1.5 turns out for about anything ever made. Adjust in 1/4 turn increments and decrements for optimum throttle response off of idle. Youll have to elevate rear wheels for this adjustment normally done in neutral.

The electric choke works like a coolant thermostat. The little "pill" with two wires connected to it is a little heater element, driven by the stator when your machine is running. The little coil expands and contracts, opening and closing choke plunger acccording to how much it gets heated by the "pill" in there. Since it goes by temperature of the coil that moves the plunger in and out, and does not sense actual motor temperature, they dont work very well other than continuous running, especially in cold weather. If you unplug it, it is choked all the time. You can replace the choke with a cable operated plunger from some other Mikuni carbs, such as the TriZinger type. You can also get an aftermarket (Delorto)carb with a manual choke lever kit for around $100. The stock choke setup performs exteremly poor in cold weather especially. The manual Delorto resulted in immediate quick and easy starting all year round.

Thank you!
It is absolutely amazing on some of these engineers decide to make things. Making a choke this complex is absolutely unnecessary and not cost effective if you ask me. Is the Delorto carb a reliable piece and worth the money?
Thanks In Advance!
